Reviews of the Gamera 3: Revenge of Iris

Yes, simply the finest daikaiju eiga made since the original Godzilla. Not only a film that can make you take Gamera seriously, but one that makes you take giant monsters seriously as well. Great story, fine acting, clever script and story, excellent directing, brilliant special effects.... this is the only one (so far!) that has it all.
